Furuta et al. (2012) found that the IL-17 levels in serum from DHF patients were significantly higher than those in DF patients or in healthy subjects. Non-Structural-1 (NS1) titers could be used to predict the occurrence of DHF (Huhtamo et al., 2010; Laurent et al., 2010; Singh et al., 2010). The gene discussed is IL17A; the disease is Dengue hemorrhagic fever.
